           Summary: ETQW: Enabling "Soft Particles" causes major
                    performance issue
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: sa@whiz.se


Enabling the option "Soft Particles" in the game Enemy Territory Quake Wars
causes a major performance drop to ~ 1 fps, CPU goes to 100% so I'm guessing
some sort of software fallback is hit?

Options → Settings → Advanced → Soft Particles

I'll see if r300g has the same problem, if so it's probably a more general
problem.

It does the same with r300g on rv350. I found that this feature is blacklisted
on ATI cards (the option is grayed out on windows), but Mesa rX00g is not
detected as an ATI card.

That's good to know, I guess this can be closed as NOTOURBUG unless somebody
thinks otherwise.

I don't think there's much reason to keep this open.

Now I tried it with mesa master on a barts pro, and soft particles don't cause
any noticeable slowdown.
